Answer:
Therefore we need 475 milliliter of Compound A
and we need 760 milliliter of compound B.
Step-by-step explanation:
i) let x be the number of milliliters of compound A
ii) let y be the number of milliliters of compound B
iii) It is also given that x = y
iv) therefore x + y = 1235 milliliters
v) therefore y + y = y = 1235 y = 760 milliliter
vi) therefore x = 1235 - 760 = 475 milliliter
Therefore we need 475 milliliter of Compound A
and we need 760 milliliter of compound B.

Answer:
176.7 square feet
Step-by-step explanation:
Diameter, d = 15 feet
radius, r = d/2
r = 15/2 = 7.5 feet
π = 3.142
Area of the pool = area of a circle
= πr^2
= 3.142 * 7.5^2
= 176.7375
to the nearest tenth
= 176.7 square feet
There can be more than one solution to system of equations.
Answer:
Volume of the mold is .
Step-by-step explanation:
